how often to harrow school?

[L&M]

I am very lucky to have a good quality outdoor school with a cushion ride surface. It never floods or gets deep, but have always wondered how often it should be harrowed/graded.
I have a few liveries, and at the moment it is probably used for 1 hour a day in the week, and possible up to 3 hours on a Sat and Sun. There never seems to be a big build up at the edge and the only times you can see footprints is when client has been jumping.
Is once a week about right?
Thanks in advance

Mine is 60 x 40, used by 15-20 liveries a day and I level it 2-3 times a week.

do it as often as you can- the more the better.
